PePS is a collaborative effort funded by multiple sources to promote and assist energy conservation programs in governments around the world. Four non-profit organizations are collaborating to direct the effort:

  • Lawrence Berkeley National Laboratory, a research institution of the U.S. Department of Energy;
  • Alliance to Save Energy, a U.S.-based consortium of manufacturers and service providers engaged in the energy efficiency business;
  • IIEC, a global non-profit working to bring sustainable energy solutions to developing countries and economies in transition; and
  • ICLEI, an international association of local governments implementing sustainable development.

Using the experiences from the U.S. Department of Energy’s Federal Energy Management Program, Mexico's federal energy conservation agency CONAE, and other successful efforts as models, PePS aims to promote energy-savings efforts ranging from efficient product purchasing initiatives to performance contracting.
